The Champ was released at the end of 1988 as a boxing simulation that was even endorsed by the World Boxing Association (WBA). It also featured a sampled music piece from the movie Rocky. Markus Grimmer had organized a license. The game came in a sturdy box with a booklet in several languages and a keyring with boxing gloves. It was LINEL’s only game that was ported to all possible platforms at the time. Besides the original Amiga release, there were Atari-St-, C64-, Spectrum-Z- and Amstrad-CPC-releases! Amiga and Atari versions came on disks, while the other versions came on tapes and big floppy disks. Markus Grimmer produced the boxes and disks in England after working with young Swiss and German developers on the game, who mostly worked from home. Christian Haller was the main coder. The game was distributed all over Europe and in the USA, and promoted at fairs by Grimmer and Haller, and in game magazines.

The game's introduction is well presented and accompanied by the iconic music from Rocky. It promises to be an action-packed boxing game. The gameplay comes as a short career path for your boxer. You can take your boxer to the top. You start off fighting in an alleyway covered in graffiti and torn posters, before finding a manager who will guide you to the training arena. Here, you must practise punching the bag, sparring, and skipping. Each player has a morale and condition factor that decreases as each successful punch rings home. Eventually, you will progress from small-scale fights to title contests. There are 11 moves in total, including high and low punches, as well as defensive moves and escapes. Full knockout rules apply, and fighters automatically break free from grappling situations.

Some of Linel's games were released in multiple languages. The game, The Champ, even had a multilingual booklet. The game itself, however, had no language, so LINEL was able to design its booklet with manuals for all languages and use the same packaging for all countries.

The reviews strongly vary. Overall, it received good ratings for its solid presentation, which included a helpful manual explaining the rules and history of boxing. Tony Dillon writes in CU Amiga: "The Champ is polished; it's amazingly professional and full of brilliant little touches. The referee counts the knock-downs, the boxers fight realistically, the soundtrack is brilliant, and the graphics are amazing." However, like other critics, he admits that the gameplay is somewhat lacking. "For a start, half the punches only seem to work half the time, and secondly, the game is far too easy.' What sort of challenge is there if your opponent just keeps falling?" In Amiga Computing, Andy Smith notes as good things that the referee darts around the ring and gets in the way sometimes, and that the game has an impressive action replay: „Following a knockout, you are treated to a nicely executed TV-style action replay, complete with ‚motion blur' effect as the boxer crashes to the canvas.“ The game's introduction is well presented and accompanied by the iconic music from Rocky.
